Whats gastric metaplasia?

In brief:
Abnormal esophagus

"metaplasia" describes transformation of one tissue type to another. In the lower esophagus, which is lined by squamous epithelium, abnormal exposure to gastric acid juices from reflux can lead the epithelium to convert itself to the kind of glandular lining seen in the stomach.

This can be a pre-cancerous change.
